Huge pines that seemed to reach to the sky.I found out that Katie loved biology too. We talked about the trees and the other wildlife we had seen so f...r. Eventually the conversation switched.Katie said, "Will have you heard all the noise at night?" What do you mean?" I mean the sounds coming from Justin, Sherry, Joe and Barb's tents." I know. It's driving Jon and I crazy. I wish I knew what sex was like. But I'll never know. Who would want to go out with some nerd like me."Katie gave me a funny. I smiled. She also smiled. I proceeded to lock the door. I had a night lamp on. So I lied down and she lies down beside me. I couldn’t control my smile.I tried to fake my sleep. I couldn’t believe that it was happening. Then without warning, she just puts her hand on my dick. I almost jumped with surprise. I looked at her. She was not smiling, just looking very serious. She said that she was in the middle of fucking her bf when he left. So she needs to finish. I just couldn’t believe that I was. "oh wow." i murmured, "stand up for me." dee rose up and i grinded my hips into hers, and she grinded back. it was so slick and slippery, hardly any friction at all. dee looked up at me, smiling happily, and said, "fuck, you turn me on. let's get in the shower!" the shower in her master bath is 5 ft by 5 ft. its huge, with clear glass front and gold tile up the walls. big enough that it didn't need a door. dee stepped in through the opening and turned on the water that came out of three shower. I pulled her hair hard so her mouth had to leave mine and as she grunted her breasts heaved. I leaned down and kissed and bit at her cleavage. Her tits were much smaller than yours.I dropped her from my arms and turned her around so she faced the wall and I pressed her hard against it. First with my whole body then just my hands as I pulled up her skirt and pushed my hand inside her panties and used my fingers to penetrate her. She moaned repeatedly as I fucked her with my fingers, her face.
